Power factor correction: A guide for the plant engineer
Effective November 2020 Capacitor banks Technical Data SA02607001E Supersedes August 2014 and harmonic filters Power factor correction : a guide for the plant engineer Contents Description Page Description Page Part one: Power factor Part two: Harmonics What is Power factor ?.. 2 Introduction.. 17. Should I be concerned about What are harmonics? .. 17. low Power factor ?.. 3 What are the consequences of high What can I do to improve Power factor ?.. 3 harmonic distortion levels? .. 18. How much can I save by installing IEEE 519 .. 18. Power capacitors?.. 4 How are harmonics generated? .. 19. How can I select the right capacitors What is the relationship between Power factor for my specific application needs? .. 8 correction capacitors and harmonics?.. 19. How much kVAR do I need?.. 8 How do I diagnose a potential Where should I install capacitors harmonics-related problem?
140 kVAR, 480 V capacitor cost: $1600 (installation extra) . This capacitor pays for itself in less than eight months . = 412 corrected billing demand 0.97 400 460 kVA × $4.75 = $2185 / month –$1957 $ 228 / month savings × 12 $2736 annual savings Case 2 Assume the same conditions except that: 400 kW @ 87% = 460 kVA
